how to use hdfs in distributed t2t

[colmantse]

I am working on distributed t2t and i managed to set up to run in nfs environment but when i change to hdfs path, it gives the log as attached. I would like to confirm if setting environment variables and changing to hdfs is enough for t2t to use hdfs or if i am missing anything more.

umm.... is there any successful use case of using hdfs in t2t that i might follow? i solved the unable to load error but the socket timeout problem persists...
